Analog Accessories by KAB
The KAB SpeedStrobe was designed to replace and improve upon older strobe
designs that relied on power line frequency. We also wanted something that was easier to use and included the ability to actually measure small amounts of
error. Not just a go - no - go - test.
The KAB SpeedStrobe features a quartz locked illuminator with 99.99% accuracy. And since it is battery
operated, it works everywhere. No need for 50 or 60 Hz versions. The Disc is silk screen printed on durable 20 mil PVC.
Instead of hypnotic bars,
the KAB SpeedStrobe features the actual speed numbers. In use, the desired speed is read directly from the disc. no searching for the right band. Covers
16.66, 33.33, 45, 70.59 - 90 RPM. By timing the drift of the display over one minute, accuracy can be measured to 0.03%
The really great features
to take note of with the KAB SpeedStrobe is the ease of use and absolute accuracy.
The KAB SpeedStrobe is unique in 2 ways. First, it does not
rely on line frequency like other strobe discs. We have heard our share of stories that confirm what we have always suspected: line frequency variations are
common. And if your turntable uses a hysteresis synchronous type motor, it will be susceptible to speed variations.
Second, conventional strobe
discs use a series of hypnotic bars that "freeze" in motion when the turntable is at the correct speed. Thats fine for a turntable that can adjust
its speed. But have you ever tried to time those marks so you can measure accuracy? It is nearly impossible. The KAB SpeedStrobe disc uses large easy to read
numbers. It is very easy to time the drift of this display. This lets you measure fixed speed turntables and determine their accuracy.
